SPEKE'S GAZELLE 

 Gazella spekei, Bly. 



Somali name, Dhero 



Description. — Speke's gazelle is by far the commoner of the 

 two gazelles known to the Somalis by the name " Dhero." It 

 is often known as the " plateau gazelle," as distinguished from 

 G. pehelni, which is the lowland or maritime variety. The general 

 colour is brownish fawn above and white underneath, the latter 

 being separated from the former by a distinct lateral dark, dusky 

 brown band. It is somewhat smaller than G. pelzelni^ Kvxd differs 

 from it mainly in possessing on its nose a peculiar corrugated 

 protuberance, which it can inflate at will. This protuberance, 

 which, when uninflated, has the above-mentioned corrugated 

 appearance, consists of two cavities, lying side by side and com- 

 municating separately with each nasal cavity, and also by a 

 common opening with each other.
